Cell tower lease sold?!

[Zander Kempf]

Here is an interesting one for you:

I have a 4-plex under contract that currently has a cell tower on the roof. Looking at the disclosures, the owners set up leases to telecom companies for the tower and then sold the leasing rates for the next 30 years for a lump sum to a third party. The annual lease rate was 20K and they sold it 10 years ago for 300K. now that I am purchasing the property and the leasing rate has already been sold I feel as though I am missing out on a significant revenue opportunity and assuming a lease that I'm not getting paid for. The numbers for the property are solid with some value add opportunities so the deal is certainly worth doing, it just seems like we're leaving money on the table. Any suggestions?
